Complete genome sequence data of Leuconostoc mesenteroides KNU-2 and Weissella hellenica MBEL1842 isolated from kimchi

Kimchi, a traditional Korean fermented food, contains many lactic acid bacteria. Leuconostoc mesenteroides KNU-2 strain with low-temperature tolerance and Weissella hellenica MBEL1842 with antibacterial activity were isolated from kimchi. The genomes of L. mesenteroides KNU-2 and W. hellenica MBEL1842 are composed of one circular chromosomal genome of 1,973,419 bp (37.9% G+C content) and 1,887,056 bp (37.9% G+C content), as well as four and one plasmids, respectively, The sequence data of the strains were deposited in GenBank under the accession numbers CP089782 (L. mesenteroides KNU-2) and CP086020 (W. hellenica MBEL1842).

Genetics: General Specific subject area Genomics and Molecular Biology Type of data Table and Figure  How the data were  acquired The PacBio RSII platform was used for genome sequencing. PacBio long-reads of L. mesenteroides KNU-2 were assembled using RS HGAP(v3.0) and annotated using Prokka (v1.12b), while those of W. hellenica MBEL1842 were assembled using FALCON (v. 2

Value of the Data
• The genome sequence of L. mesenteroides KNU-2 and W. hellenica MBEL1842 provides fundamental knowledge about genes related to lactic acid bacteria isolated from kimchi. • The genome data of the strains will be useful for comparative genomic analysis with other lactic acid bacteria. • The data can be useful in understanding the characterization of enzymes and genes related to kimchi fermentation.

Data Description
Kimchi is a traditional Korean fermented food consisting of vegetables such as Chinese cabbage, radish, and various ingredients [3] . Lactic acid bacteria (LAB), such as Leuconostoc, Lactobacillus , and Weissella genera, play an important role in kimchi fermentation [4 , 9] . Therefore, LAB are considered fermentation starters that produce standardized, high-quality kimchi [9] . L. mesenteroides KNU-2 strain with low-temperature tolerance and W. hellenica MBEL1842 with antibacterial activity were isolated from kimchi.

Experimental Design, Materials, and Methods
The L . mesenteroides KNU-2 (KCTC18324P) and W. hellenica MBEL1842 strains were cultured in MRS (de Man, Rogosa and Sharpe) broth at 37 °C for 24 h. Genomic DNA was extracted from the strains grown to an exponential phase using the G-DEX TM IIc Genomic DNA Extraction kit (iN-tRON, Daejeon, Korea). Whole-genome sequencing was performed using the PacBio RSII platform (Pacific Biosciences, CA, USA). If it was estimated that the total number of bases in the PacBio reads would result in less than 100 × genome coverage, additional sequencing was performed, and all the output raw data were used for assembly.
The ANI values for closely related species were calculated using the Orthologous Average Nucleotide Identity Software Tool (OAT). Whole-genome alignment of strains was visualized using the CLC Genomics Workbench 20.0.4 (CLC bio) software program.
